Fixing methods of railway spikes

1. Clamping fixation method

Clamping fixation is one of the commonly used fixing methods. The specific method is to clamp the raised part on the back of the spike with the wall of the track hole, and use a hammer or a check hammer to nail it firmly. This fixing method is simple and easy, but the fixing force is small and the stability of the spike needs to be improved.

Precautions for use: When clamping, ensure that the spike and the hole wall fit tightly to avoid being too loose or too tight.

2. Grouting fixation method

Grouting fixation is one of the more complex methods of fixing spikes, which is often used in heavy-loaded lines or areas with complex geological environments. The specific method is to drill holes around the nail holes, inject high-strength cement slurry, and fix the spikes in them. This method has strong fixing force, is firm and stable, and is suitable for various road conditions.

Precautions for use: Grouting fixation requires professional tools and personnel support, and rigorous operation; when grouting, ensure that the slurry flows evenly, and the storage time should not be too long, so as not to solidify and affect the fixing effect.

3. Press plate fixing method

Press plate fixing is one of the commonly used fixing methods. It is fixed in the track hole by pressing and locking the back of the spike. This fixing method is simple to construct, easy to operate and has significant effects.

Precautions for use: When fixing the press plate, ensure that the pressure is uniform and moderate to avoid excessive stretching or insufficient action.

It is important to remind that no matter what fixing method is used, it is necessary to ensure that the fixing state of the spike is correct to ensure driving safety. In addition, during the use of the spike, it is necessary to check regularly and replace aging and damaged parts in time to keep the track in good condition.

There are many ways to fix railway spikes, and each method has its scope of application and precautions for use. During use, please be sure to strictly follow the construction specifications and relevant requirements to ensure the stability and firmness of the spike on the track to ensure driving safety.
